"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

HRZ to SGI Conversion: FAQ

What are HRZ files?

HRZ is an image format associated with slow-scan television (SSTV) software. This obsolete mode of video communication implies a slow transmission of still images and is generally fitted for limited bandwidth conditions, requiring specialized software. Opening HRZ images with regular image viewers is not very likely, so for easier access we recommend converting to a more popular format, such as JPG or PNG.

What are SGI files?

SGI (Silicon Graphics Image) is a raster image format associated with Silicon Graphics workstations. It is a bitmap file that can store black-and-white, gray-scale and color images, and may also contain color maps and alpha channels. SGI files are sometimes referred to as RGBs and can either use no image compression or RLE compression. Alternative extensions for the SGI format are BW, RGB and RGBA.
